Most of our polished stainless steel u-joints are clamped down by pinch bolts. These sometimes take more then 45 ft lbs of torque to tighten them down. You can torque these pinch bolts down to as much as 45 ft lbs if necessary to tighten the joint. Our u-joints are strong and will not break. They provide the maximum angle of operation at about 38 degrees. http://www.unisteer.com/u-joints.html
